The special built-in console file in Python 2 which has an 'encoding'
attribute should qualify as a special type, since it accepts both bytes
and text faithfully.

In their infinite wisdom, the CPython developers saw fit not to
allow us a writable 'encoding' attribute on the built-in 'file'
type in Python 2, despite making it writable in C with
PyFile_SetEncoding.
Pretend they did not do that.
